CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 743,158, dated November 3, 1903.

Application filed February 10, 1903.. Serial No. 142.757. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL HERBERLa citizen of the United States,residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and useful Improvements in Oar-Roofs, of which the following is a specificatiomreference being had therein to the accompanying drawings.

The invention relates to that class of carroofs wherein metallic sheets or plates are employed. as an inner covering for the roof, the plates being arranged for independent endwise and sliding movement upon a suitable framework forming a part of the roof structure, whereby the withdrawal of one independently of the others may be effected for the purpose of repair or replacement.

The invention consists in the novel and simple means employed for retaining the sheets or plates' in place upon the framewor on which they are mounted.

The invention further consists in the pecul-v iar formation of the retaining devices for the sheets whereby in addition to holding the latter in proper position serve to cover and protect the lower ends of the supercarlines.

The invention still further consists in various details of construction of the roof, as will be hereinafter described, and fully shown in the drawings, in which-- Figure 1 is a section through a car-roof embodying my invention. Fig. 2 is a sectional perspective view of a portion of the roof, illustrating the retaining device for the sheets.

The reference-letter A designates a car, which may be of any approved construction, and B is a roof therefor. In formation the roof comprises an internal framework, consisting of carlines O, purlins D, and the inner ridge-pole E, and a similar external framework formed of 'supercarlines F, superpurlins G, and the usual superridge-pole H.

Metallic sheets H, forming the inner roof, are arranged, as shown, intermediate the two frameworks and have a sliding engagement with the supercarlines. Each sheet is pro- Vided with upwardly-extended flanges H at its side edges, and these engage within upwardly-inclined slots H formed in the lower faces of the supercarlines. The plates are also open-ended to allow of their extending gaging portions.

at the upper ends beneath the superridgepole and are adapted to have a slight endwise play independent of each other, so that the metallic covering as an entirety will be flexible, and thereby capable of withstanding strains necessarily imposed upon it. At their lower ends the plates are provided with my improved retaining devices I, which while allowing slight endwise movement of the plates for the purpose set forth prevent the slipping of the sheets from beneath the superridge-pole.

The holding devices are carried upon the lower ends of the supercarlines and abut against the portions of the sheets engaging the supercarlines. In this particular case they bear against the upwardly-extending flanges.

Preferably the devices are U-sbaped in configuration, comprising parallel members a and b and a cross-section c, the parts collectively forming a cap, which covers and protects the extreme end of the supercarline and at the same time holds the sheet in place by bearing against the lower ends of its en- These caps are secured in place by means of bolts 1', which extend through the superpurlins, the caps, supercarlines, and preferably the main facia J, as shown.

By preventing the sheets from slipping from beneath the s'uperridge-pole in the manner set forth I am enabled to use in this type of roof a superfacia K of ordinary construction spaced from the lower ends of the supercarlin es in the usual manner to form the necessary drip-passage opposite the body portions of the plates. The spacing of the superfacia is effected by securing the latter at its upper edge to the lower superpurlin, which projects beyond the lower ends of the supercarlines and at the lower edge to suitable blocks L, which are fastened to the main facia J.

While I have shown and described a particular form of retaining device, I do not desire to be limited to the same, as various changes and modifications may be made in its construction without in any manner departing from the spirit of my invention.

What I claim as my invention is-- ICO 1. In a car-roof, the combination with the supercarlines, of an inner roof formed of a series of metallic sheets or plates, having a sliding engagement with the supercarlines, and an independent retaining device at the lower end of each supercarline bearing against the engaging portions of the sheets.

2. In a car-roof, the combination with the supercar-lines of an inner roof formed of a series of flanged metallic sheets having a sliding engagement with the supercarlines, and

4. In a car-roof, the combination with the superridge-pole, of the supercarlines, an inner metallic roof formed of a series of plates slidingly engaging the supercarlines and extending beneath the superridge-pole, a superfacia spaced from the ends of the supercarlines and retaining devices intermediate of the superfacia and supercarlines and bearing against the engaging portions of the sheets.

5. In a car-roof, the combination with the supercarlines, of an inner roof formed of a series of metallic sheets or plates having a sliding engagement with the supercarlines, the facia, and retaining devices intermediate of the lower ends of the supercarlines and the facia bearing against the engaging portions of the sheets.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL HERBERT.
